minikube installation on mac

https://kubernetes.io/docs/getting-started-guides/minikube/

Notes

• production kubernetes should run on Ubuntu - version "Cannonical Distribution of Kubernetes" (Juju and conjure-up seem to be the tools to install kube)
• after running container, check status with kubectl get pod
• to check logs kubectl logs <podname>
• to check create errors kubectl describe po <podname>
• create node app docker image https://nodejs.org/en/docs/guides/nodejs-docker-webapp/
• remove exited containers to start again - https://zaiste.net/posts/removing_docker_containers/ (after tag do docker push to make it working!)

troubleshooting local docker registry to work with minikube

https://gist.github.com/kevin-smets/b91a34cea662d0c523968472a81788f7

Steps:

1. install docker (don't need to run as minikube runs it's own docker daemon)
2. install minikube, start minikube start
3. setup local registry so apps docker images created on localhost and pushed to localhost:5000 are accessible from minikube - https://gist.github.com/kevin-smets/b91a34cea662d0c523968472a81788f7
4. run kubectl create -f {filename} for mongo-service, mongo-controller, web-service, web-controller
5. run minikube service web --url to get url - open in the browser
